Question

一段英语阅读
Among people 70 and older,36% of pedestrian deaths in 2006 occurred in crosswalks ,compared with 21% of those younger than 70,according to the Insurance Institute for Highway Safety.
看完这段话,下面的这句细节选项为什么不对呢?
Among 100 pedestrian deaths there were 21 people younger than 70.

Answer 1

occurred in crosswalks 是作的后置定语,指的是死亡发生在人行横道,70岁及以上的会占36%
而Among 100 pedestrian deaths there were 21 people younger than 70.指代不明确.
